AUSTRALIAN tennis coach Josh Eagle is confident the lure of grand slam tennis will ensure Bernard Tomic casts aside recent drama and fronts up at the French Open.

Tomic's participation at Roland Garros remains in some doubt after his father and coach John Tomic indicated at a Madrid court last week he was unlikely to compete.

Australia's top-ranked man has not played a match since his father was charged over an alleged assault on Tomic's training partner Thomas Drouet at the ATP event in Madrid a fortnight ago.

Tomic has opted to continue training in Monte Carlo rather than competing this week but Davis Cup coach Eagle, who has offered to mentor the 20-year-old with his father barred from ATP events and Roland Garros, fully expects to link up with the player in Paris next week.

Eagle is working with Australians Lleyton Hewitt and Marinko Matosevic at the ATP event in Nice, France and spoke to Tomic late last week.

"I don't really expect to see him until Paris but I certainly expect him to play in Paris," Eagle told AAP on Saturday.

"It's grand slam tennis. Bernie would be jumping out of his skin to play any grand slam tournament regardless of what's happened.

"I think he'll be ready to go next week."

Should the world No.52 decide to return to competition at the French Open, starting next Sunday, he'd need to overcome a significant lack of match practice.

He will have played only one match in more than a month, a first-round loss to Radek Stepanek in Madrid.

By contrast his claycourt build-up to last year's French Open featured 12 matches in appearances at Monte Carlo, Barcelona, Munich, Rome, Madrid and Nice.

He was knocked out in the second round in Paris last year and failed to win a match at his previous two attempts at Roland Garros.

Meanwhile, wet weather in Nice could disrupt Hewitt and Matosevic's Open preparations.

Heavy rain prevented any play on the tournament's opening day on Saturday and the pair will not play until at least Monday, with more rain forecast.

Hewitt made the most of the delay as he visited the Cannes Film Festival on Saturday night.

John Tomic's trial has been adjourned until October. He denies assault and says he struck Drouet in self-defence.
